Does it make sense to use the traffic audit system for Yandex.Direct?

Question

Yandex.Direct

Greetings!
Colleagues, please tell me:
1. In order to increase the effectiveness of advertising campaigns, does it make sense to use traffic audit services (clickfrog, botscanner, etc.) for Yandex.Direct in search, taking into account the fact that Ya. the sheet can be made only 25 ip?
2. A similar question only for Direct (on thematic sites) to filter sites (there is a limit of 1 thousand domains)?
Many thanks in advance for your replies.

Answer 1

In general, there is no point, because advertising systems themselves are interested in the purity of traffic and they have a powerful anti-fraud of their own.
It makes sense to use it only if you are buying incomprehensible traffic from new dubious sources and channels.
And the quality of sites, in principle, can be monitored anyway, by analyzing attendance on them. Anything with horrible transactional/audience metrics can be turned off.
If you feel that they are clicked, you can contact Yandex support, they will check the specific traffic more carefully. If anything is found, the money will be returned.

Answer 2

You definitely don’t need to graze direct ... they also return money from clicks periodically ...
